To @ZZ 10700712, it 71u03/ concern:

Be it known that I, IVILLIAM F. OLIN, a citizen of the AUnited States, residing in the city of Chicago, county ot Cook, and State of Illinois, have invented certain new and use- `ful Improvements in Grain-Harvesters,which are fully set forth in the following specification, reference being had to the accompanying drawings, forming part thereof.

" Figure l is a partly sectional plan of a harvester embodying my invention, many parts not related thereto being omitted. Fig. 2 is a plan of a modification of the platform-conveyer frame with its connections and its operating mechanism. Fig. 3 is a vertical section through the platform on the line x of Fig. l, but showing the mechanism in a different position from that shown in Fig. l. Fig. 4 is a section on the line y y of Fig. 1. Fig. 5 is a perspective of a universal joint pertaining to the platform-conveyer and cutting mechanisms. Fig. 6 is a plan ot' a portion of the harvester-frame stripped of mech1 chanism, designed to show the mode in which the several sills and bars of the frame are joined and arranged to brace and stilr'en each other. Fig. 7 is a vertical section at the line ir af' on Fig. l. Fig. 8 is an enlarged detail plan of a portion of the linger-bar and its connected lingers and of the sickle, designed to show t-he relative arrangement of the iingers and the direction of their gatheringedges. y' on Fig. l. Fig. l0 is a front elevation of the binder-frame and driving-train. Fig. 1l is a section through the line l1 ll on Fig. lO. Fig. l2 is a section through the line l2 l2 on Fig. l. Fig. 13 is a section through the line 13 13 on Fig. l. Fig. let is a front elevation of the binder-shifting lever and connected mechanism, showing the sill upon which it is supported in section.

The harvester-frame is constructed as follows: There are two sills A A', extending from front to rear, the former on the outer side and the latter on the inner side of the drivewheel. They are connectedat their forward ends by a bar or sill A?, which crosses and is ,securely fastened to them both at their forward ends and extends thence grainward, and is united to the finger-bar B` by means' Fig. 9 is a section through the line y which will be hereinafter described. Said sills are further united by the bar or sill A3, which crosses and is iirmly secured to them both at their rear ends, and thence is bent obliquely forward and grainward, extending, without further change ot' direction, nearly to the vertical plane of the drive-wheel axis, being then again bent more grainward and extending a short distance. The last portion (L3 extends alongside of and is securely bolted to a Hat metal bar A", placed'vertically edgewise and having one end ct* bent at an oblique angle to its general extent, so as to lie alongside the sill A', to which it is securely fastened. Said bar A4 extends in the oblique direction rst indicated, forward andgrainward, and is joined to the stubbleward end of the lingerbar B a short distance stubbleward from the connection of said linger-bar to the bar A2, above mentioned.

By meansot a bracket C', which will be hereinafter more particularly described, the rear sill or bar A5 is secured to the sill A', and from said securement extends iirst at an angle ot' about forty-tive degrees tothe sill A', rearward and grainward until it reaches a point somewhat farther grainward than the junction of the sill A2 to the linger-bar, and is there bent directly grainvvard, and at its grain end is rigidly secured to the grainward or divider sill or bar A. Said divider-sill A extends from its securement to the rear sill A5 f )rw ard, with a slight grain ward Obliquity, and crosses and is secured to the finger-bar at the grain end thereof, and, extending forward of it, is provided with the usual appliances of a divider. Ihere the rear sill A5 crosses the obliquely-extending portion of the sill A3 it is preferably rigidly secured thereto, and it may be secu red, also, at its intersection with the bar A1.

Upon inspection ot' this trarne it will be seen that the triangles formed, first, by the sill A', bar Ag, and bar A", taken with the short portion ot' the finger-bar which completes Ithe junction between the bars AL and At, second, by the sill A', bar A", and bar A3, and, third, by the sill A', bar A3, and sill A5, make a structure which is very rigidly braced against fore-and-aft strain which might tend to result from rearward pressure or resistance IOO to forward motion encountered by th"e iingerbar. To further stiften this structure, the bar A4 is connected to the sill A5 by the bar A7, which is secured to bar A4 near the junction of the latter with the finger-bar B, and to the sill A5 at a point grainward from the bend d5, where it turns directly grainward, thus making an irregular triangle, of which bar AT forms one side, the bar A3 forms another, and the bar A4 and the portion of the bar A3 from its intersection with sill A5 to its junction with bar A4 forms the third side. The triangle formed by bars A2 and A4 and sill A is also stiffened by the brace A8, which is secured to bars A4 and A2, and affords securement for certain brackets, which afford the bearings for the gearing, as will be hereinafter specifically explained. The bar AT is further stiffened by the bar A, which extends from the first-named bar to thesill A5 at a distance from the forward end of bar A7 about one-third of its length, and from said bar A9 is extended the bar A10, which crosses and is rigidly secured to the bar A4,

,thereby stiffening it.

For convenience of reference hereinafter the sills A A and the front sill A2 and rear sill A5, said four sills inclosing the wheel, may be referred to as the wheel-frame, and the sill A5 and the oblique portion of the sill A3, the bar .A4, and the finger-bar, and the various braces, bars, and sills which stiffen and connect these several parts may be referred to as the platform-frame.

D is the drive-wheel. D is the masterwheel, rigid therewith. The drive-wh eel axle is journaled in a journal-box c on the sill A, and in a suitable bearing provided inthe bracket C', which is secured to the sill A and affords securement, as above stated, for the rear sill A5. To the sill A there is secured, also, the bracket C2, which has a bearing for the shaft of the main driving-pinion D2, which meshes with and is driven by the master-wheel D', said sha-ft d2 having secured to its grainward end the beveled gear-wheel D5. Said gear-wheel meshes with and drives the beveled pinion D4, whose shaft (Z4 has a bearing in the bracket C2.

C5 is abracket, which is secured to the ba-r A40 and to the brace A8. It has a bearing C50 for the shaft d4, near itsforward and grainward end, and said shaft carries at that end the beveled gear-Wheel D5, which meshes with and drives the beveled gear D, which also has a bearin g C31 in the bracket C5, and meshes with anddrives the beveled gear D5, fixed on t-he stubbleward end of the shaft cl40, which has a bearing C32 in said bracket C3 in line with that of the shaft d4. The purpose of the beveled gear-wheel D' is to communicate power to the binder, and its further bearings will be hereinafter explained.

The bars A2, A5, A5, and A5 andthe fingerbar B are all made of angle-iron, having one iiange vertical and the other horizontal, thereby affording convenient surfaces for the The bracket C has aiian ge which is secured to the horizontalfiange of' the bar A2, and is formed with an angle portion which fits into the angle of the finger-bar B, to whose vertical flange it is bolted. This bracket has the bearing c for the grainward end of the shaft dw, said bearing being above the securement of the bracketv to the bar A2. To the end of the shaft d4, grainward from the bearing c, there is secured the beveled gear-wheel E, which meshes with and drives the bevel gearwheel E,which has integral with it the crankwheel E2, and between the two parts E and E2 the combined crank-wheel and bevel-wheel is journaled in a suitable j ournal-box provided in the bracket C above its secureinent to the finger-bar, the beveled gear part E being in front of the said journal-box and of the iinger-bar, and the crank-wheel E2 being behind the finger-bar B. in the are of a circle, about a center located at the rear of the platform in the vicinity of the rear sill A5, some distance grainward from the bend a5. As illustrated, (and preferably,) the chord of the arc to which the finger-bar conforms from its intersection with the inside divider to its intersection with the outside divider is substantially at right angles to the direction of advance of the machine.

The fingers b are formed with their edges, respectively, which are on the side farthest away from the middle of the length of iingei-,

bar approximately parallel with the direction of travel, except the middle finger b, which has both edges alike an d equally converging toward aline through the point of the finger in the direction of travel. This construction makes only the edges, respectively, of the fingers on the side toward the middle finger b act as gathering-edges for the grain, the other edges, by reason of extending in the direction of travel, having no tendency to gather the grain laterally. The fingers on the grainward side of the middle iinger therefore tend to tip the grain stubbleward as they part it, and those on the stubbleward side of that middle finger tend to tip the grain' grainward. This tipping effect being produced before the grain is severed tends to cause it to fall onto the platform with the heads converging, and that is the purpose of this feature of the construction.

F is the sickle. It is curved to conform to the finger-bar B, and is convenientlymade of angle-iron bar, with cutters on its horizontal flange. It lies in the angle of the similar but larger and heavier angle-iron which forms the .finger-bar. i

At a point preferably near the middle of the length of the sickle there iis bolted securely to it the radius-arm F', which is flanged or extended into the short cross-arm f at the forward end, for the purpose of re- The finger-bar B is curved IOO IIO

ceiving the fastening bolts, and extends thence rearward across the platform from front to rear, and at the rear end is pivoted on the rear sill A5 at the center of the arc, to which both the finger-bar and the sickle are conformed. The pivotal connection of the radius-arm F to the sill A5, I make by providing a vertical spindle or pivot f rigid with the radius-arm F', across the end of it, and providing a bracket N, secured to the sill A5, and having suitable step and crown bearings for the ends of such spindle. This bracket F2, l make open between the said spindle-bearings, and to the spindle f', between the said bearings, l pivot on a horizontal pivot the radins-lever F3, which extends thence forward, the Yforward end being lodged in the bearing eccentrically located in the crank-wheel F2. The spindle f and the horizontal pivot of the lever Fi3 form a universal joint for said lever. It should be observed that the axis of the wheels l E2 is radial to the curve of the finger-bar and sickle, and if produced would intersect the axis of the pivotal spindle f.

Upon the radius-lever F3, a short distance rearward from the crank-wheel E2, there is clasped the twopart pitman journal-box. E3,

and to said journal-box, which has a suitablev ear or lug ef for that purpose, there is connected the pitman or link E4, which is connected to the lug f1" on the radius-arm F. The points of connection of the link E'1 to the radius-lever F'n and to the radius-arm F are preferably equally distant Vfrom 'the pivotspindle f. The rotation of the crank-wheel E2 causes the radius-lever F3 to describe a cone whose apex is the point of intersection of the horizontal pivot cf the said lever with the axis of the spindle f', on which it is pivoted, and at the same time to turn that spindie back and forth on its vertical axis, while the pitman-link E* gives an oscillatory inotion to the radius-arm F', which motion itwould also receive if sufficiently rigid and rigidly connected to the spindle f from the axial oscillation of the latter, and by said oscillatory motion ot the said radius-arm F' the sickle F is reciprocated back and forth in the are in which it extends. lf it is not convenient to connect the pitman-link E" with the radius-arm F and the radius-lever FS at points equally distant from the spindle f', the radius-arm should be pivotally and not rigidly connected to the spindle; but when the pitman-link is connected, as illustrated, at points equally distant from the spindle f the horizontal movement which would be communicated by the lever F3 through its connection with the spindle to the radiusarm F is not different from that which would be communicated by the link El to a greater degree than the necessary play of the joints will accommodate, and the arm F may therefore be rigid with the spindle, as shown.

The platform under decking G is secured in any convenient manner to the frame-bars A5, A, and A7, and to the linger-bar. Preferably cross-bars G extend from the rear sill to the Alinger-bar, thereby further stiffening the frame and affording securement for said decking, and the upper decking G3 is supported upon said under decking by blocking or ribs G2, located between the concentric feed-bars Il. The said upper decking is slotted in arcs ot' concentric circles about the spindle f', and the `feed-bars 1l are made of metal strips curved to correspond, respectively, to the said curved slots in the deck, and having grain-feeding teeth or fingers projecting through the slots g of the upper decking. lf the feed-bars ll could be made absolutely rigid and could be rigidly connected to the radius-lever F3, the conical movement of said lever would give to the feed-bars throughout their entire length the movement which is desirable-namely, rising and falling through the slots g and reciprocating in curvilinear paths within said slots-the grainward ends having precisely the same movement as the stubbleward ends, and thus feeding the grain with the same grasp and speed; but it is not possible to make said bars sufficiently rigid, nor to secure them with sutticient rigidity to the lever F3 to prevent the grainward ends of said barsfrom dropping down and failing to engage the grain, and hence other means have to be resorted to to give both ends substantially the same movement. The means which I adopt for this purpose consist of the radius-levert, which is connected to the pivoted spindle f in the same manner as the radius-lever F3. From the spindle f the lever F5 extends nto the vicinity of the fingerbar and receives a movement substantially the same as that of the radius-lever F3, such movement being produced by means of the lever F and the feed-bars themselves co-operating. The lever F is pivoted upon the frame at f6 and passes through the slots and f5 in the levers F3 and F5, respectively, to make sliding pivotal connection with said levers, the distances from to ff and f', respectively, being proportional to the distances from]C3 to f and f', respectively. The feedbars are loosely connected to the radius-lcvers F:s and F5, and kept from moving longitudinally with respect thereto by suitable stop-pins or collars 7L, The lever F5 will receive the same vertical movement as the lever F3 by means of the lever F, and will receive the same horizontal movement as the lever F: by means of the feed-bars H, and these two movements being simultaneously communicated give to said lever F5 the resultant rotary movement, substantially the same as that of the lever FS. Thus the two ends ot' the feed-bars H, receiving substantially the saine movement, take the same movement throughout their entire lengths. Since the lever F6 is designed to communicate to the lever F5 only the vertical movement of the lever F3, its sliding pivotal connections to both levers F3 and F5arebylongitudinal slots IOO and from slot f5 to spindle j" and pivot f5,

f3 and f5, as described, and bymeans of those slots the levers F3 and F5 play to the extent of their horizontal movements on the lever F5. To keep the lever F6 in the proper vertical plane, a guide F50 may be provided at will occur at thoseY points,and the levers F5:

and F5 may be rigidly connected together and provided with 'a'common pivotal connection to the spindle f without in any respect altering the movement of the feed-bars.

A preferred modification consists in making the lever F5 without any pivotalaction upon the levers F3 and F5, and connecting these rigidly-joined levers by a single hori- Vzontal pivot to the pivot f', and providing a sliding pivotal connection for the lever Fo'n the frame. This construction, which is shown in Fig. 2, makes all the'parts F3 F5 F6 and the feed-bars H move as one rigid structure, and they are therefore shown as rigidly united. In this construction the parts F3, F5, andl FG may be considered as constituting a frame for the support and actuation ofv the feedbars H.

In defining the relations between the distances from slotf5 to spindle fand pivot f5,

the mean position of the levers F3 and F5 on the lever F6 and of said lever F5 in the slots are the positions to be considered and in the structure shown in Fig. 2 the slotin which the lever or lever-arm F6 gets its sliding pivotal action should be located in the horizontal plane of the pivot of bars F3 F5 to the spindle f and in a` horizontal line through said pivot parallel to the chords of the arcs of movement of the feed-bars H.

It will be obviousthat any number of leverarms rigid with the rigid structure composed of bars F5 F5 F and the feed-bars H might be extended through sliding'pivotal bearings in line with that of the lever F5, and that such additional arms so connected would not alter the movement of this structure. One such additional arm FT is shown in dotted lines in Fig. 2. Inspection of this structure will make it evident that the action may be considered.

F5 is also correctly described as last above stated, and this maytherefore be considered the most generic conception of the movement. The parts F5, F5, and F6 in both theforms described are bars having the function of connecting the feed-bars and forming a supporting-frame for the same; but parts F5 and F6 cease to be distinctly'levers when they are made rigid with part F3, as in the structure shown in Fig. 2, wherein they become in effect arms of part F5, which in that structure, as well as in the other form illustrated, operate as a lever.

It will be obvious that only so much of the wheel E2 Yas Ywould makeuipt a crank-arm reaching to the bearing e2 is essential to the movement produced,and in referring to this wheel vin my claims I design to include only so much of it. i

The operation of this mechanism is, first7 as described, by reason of the form of the fingers, to cause the grain to fall upon the platform with the heads'converging toward the pivot f Since the stroke or 'movement of the feed-bars H is greater in proportion to their distances forward of that pivot, their action upon the grain wheels the grain about that pivot and accumulates it at the stubble side of the platform in a position oblique to the line'of travel vof the machine, and this is accomplished without employing any special devices for turning the grain in addition to the platform-conveying mechanism above described.

In view of the operation of this mechanism it is thought important that the grain should, if possible, be caused to fall upon the platform with the heads converging, as described, and in addition to making the fingers b of the form described, whereby they tend to lean the grain before it is severed, I construct the reel so that it will tend toproduce a like result by making its bats R in curved form, substantially conforming to the curvature of the bar and sickle. The bats thus formed are secured to the reel-arms R in such relation thereto as respects the direction of their curve that each bat will be approximately parallel to the sickle at the position which the bat occupies when the grain engaged by it is being severed. Obviously, this position will vary somewhat as the reel is adjusted to the different conditions and heights of the grain; but the variation is not sufficient to prevent the attainment, substantially, of the result sought.

I have in the drawings made no illustration of any mode of adjusting the reel, since that does not pertain'to my present invention, and the construction of the reel and its driving mechanism, which I have shown, except as respects the curved bats described,v is merely conventional, and I design such curved bats to be applied to any form of reel driven by any desired mechanism. In the drawings I have simply shown the reel-shaft R2 journaled in standards R3 and R4, secured to the IOO IIO

forward frame-bar A2, said reel-shaft having at its end the sprocket-wheel r2, which is driven by a chain PJ, which receives its motion from the sprocket-wheel F on the drivewheel axle.

Vhen concentricallyoperating conveying devices are combined with a straight sickle and located behind it7 difficulty is experienced because the grain cut at the grain end of the sickle and falling prestrate behind it if swept in the curved path ofthe devices has its butts carried forward of the line of the cut at the middle part, and provision must be made for moving the grain endwise to prevent this difficulty. By curving the sickle in conformity to the curved path of the conveying mechanism this difficulty is avoided, and by cmploying such concent-rically-operating conveying devices immediately behind the sickle I am able to utilize the entire width of both the platform and whatever parts may necessarily intervene between it and the drivewheel for turning the grain tothe desired position and binding it. The bar Aw is made of round iron pipe, and parallel to it at a little distance stubbleward is secured a similar tubular bar All. Both of these bars are secured at their rear ends to the bar Ai and extend a considerable distance forward of the bar A", to which they are also secured. Their direction is substantially parallel to the oblique line at which the feed-bars H deliver the grain-that is, parallel to a radius through the pivot f and the stubbleward end of the forward bar ll at its most stubbleward position. Upon these two bars A10 and A the binder-frame is supported and adapted to slide. Said bind er-frame is of the usual form, having two parallel horizontal arms L and L2 connected by the standard L. From the standard L there are extended at the forward end t-he bracket-like arms L2U and L21, and from the lower arm L2, at the rear end, the arms L22 and L22', which afford the bearings of said frame on the bars A10 and AH. From the forward lower corner of the binder-frame there is also extended the arm orbracket L24, which affords a bearing Z24 for the forward end of the shaft M. Said shaft M has another bearing near its rear end,which it obtains in the bracket This shaft M is the shaft of the beveled gear-wheel DG. It is square between its bearings in brackets L2L and L25 and slides through the hub of the wheel D, which has a corresponding square opening.

At the rear end of the shaft M is secured thewheel, from whose shaft power is communicated to the remainder of the binder mechanism, all of which is of familiar character and not illustrated in detail and need not be herein described.

Upon the sill A there is secured a bracket N, at the upper end of which there is formed the notched segment N. ln this bracket N there is journaledthe vertical rock-shaft n, which has at the upper end the lever-arm N2, which extends stubbleward in convenient reach of the driver from the seat, and at-the lower end the lever-arm N2, which extends grainward and is connected by the link N1 to the binder-frame, to which said link is pivoted at at. The locking-dog n.2, operated in familiar manner, as illustrated, is connected to the arm N2, and engages the segment N. By means of said rock-shaft and its lever-arms. the binder may be moved back and forward, sliding on the bars A1U and All, and by means of the dog4z2 and segment N may be locked at any position desired.

By extending those of the feed-bars H, which are rearward from the vertical plane of the needle stubbleward nearly to the vertical plane of the needle rock-shaft l make them serve as packers, dispensing with a separate packer behind the needle.

Upon the oblique portion of the sill A5, which extends, as already stated, from the vertical plane of the drive-wheel axle obliq uel y grainward and rearward, and which, as illustrated, lies at an angle of aboutfortyfive degrees to the axle, I mount in suitable brackets ao and alhone at each end, t-he rockshaft P. This rockshaft I provide with crankarms P', of which the forward one is the longest and the rear the shortestand the intermediate ones of intermediate lengths. To the ends of these crank-arms are pivoted arms P2, which are slightly bent near their pivots p2, so that their direction is somewhat more nearly rearward than the vertical planes of the cranks P. These arms P2 toward their rear ends are bent so that they terminate almost directly rearward, as illustrated. The cranks P normally extend almost horizontally toward the binder and conveyer platform, and the arms or bars P2, extending from their pivotal connections p2, lie on top of the shaft P, so that said arms P2 also normally extend almost in a horizontal direction. At the stubbleward and forward ends of the shaft P it is provided with a lever-arm P2, by means of which the shaft P maybe rocked in its bearings; and the bracket am has formed upon it the notch (L52. A suitable lockingdog p3, operated in the customary manner, is provided to engage said notch.

Around the shaft P, between the foremost crank-arm P and the bracket ai, is coiled the spring P1, one end of which is secured to said bracket and the other to said crank, the spring being coiled in such direction as to tend to rock the shaft to carry the arms P over toward the binder. This structure, comprising the shaft P, crank-arms P, and arms P2, constitutes a sheafcarrier,onto whose arms P2 the bundles are discharged from the binder. W hen any desired number of sheaves are accumulated on said arms, the driver Will release the locking-dog p3 from the notch (L52,

TOO

and the weight of the bundles overcoming the tension of the spring P'l will cause the carrier-arms P2 to descend and allow Ithe bundles to slide off to the ground. As soon as the bundles are discharged the spring P4, 1eacting and being sufficiently strong for that purpose, will rock the shaft P, throw the crank-arms P back to their horizontal position, and ,lift the carrier-arms P2, also, to their original position, ready to receive a new load. In the dumping movement of the carrierarms they slide and rock over the shaft P until their rear ends touch the ground, and then are lifted at their opposite ends, where they are pivoted to the cranks P until said ends stand vertically above the shaft P distances equal to the lengths, respectively, of said cranks. They therefore are caused to stand at asteeper inclination than if they were merely pivoted over the shaft P, or were rigid with it and tipped by it, the length ofisaid cranks being added to the height of the shaft P from the ground in giving them their inclination. It will be seen that this structure permits the bundles to be discharged with theirbutts in the rear of the drive-whcel,and by reason of the curvature of the ends of the carrier-arms P2 and the greater lengths of the forward cranks P the butts of the sheaves are caused in the process of dumpy ing to be turned round, so that they will lie upon the ground almost at right angles to the Vdirection of travel, as if discharged directly rearward. It. will be noticed, also, that no action of the driver is necessary either to dump or restore the carrier Vexcept the releasing of the locking-dogp3, the dumping being then effected by the weight of the bundles, and the restoration being effected by the reaction of the sprin g P4 after thebundles are discharged.
